I got some samples from MAXIM some few days ago. Since I was busy studying other stuff I had no time to give them a try. Today I tried the DS1626 Temperature Sensor.

It was very easy to setup in the Arduino environment using the SoftwareSerial library. One problem I had was, that I was not able to write the temperture to my LCD display. I could not figure out why this happens. The LCD code didn’t worked anymore when including the SoftwareSerial header without using any functions of it…

Another problem for me was, that the DS1626 is being delivered in a SOP8 package and I for the first time needed to solder SMD. I used an adapter for SOP28 to DIP28 conversion because I wanted to place the IC on my breadboard. I soldered it successful and it worked right out of the box… ;)

I added my LM35 Temperature Sensor to my Arduino again and added a display to show how hot it is… ;)

I have used the LM35 already some month ago; It is a very easy to setup device.

Here is my Code:

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

float temp;
int tempPin = 0;

void setup() {
  lcd.begin(16, 2);
  lcd.print("Temperature:");
}

void loop() {
  temp = analogRead(tempPin);
  temp = temp * 0.48828125;
  lcd.setCursor(0, 1);
  lcd.print(temp);
  delay(1000);
}

Have fun with it… ;)

The Arduino and the Netduino are communicating over two digital IO lines. The animation is being synced over these lines. Rafel an I wanted to make the displays run. With success… but what next? Syncing both devices!

Since Rafael is developing on the Netduino platform and I am using the Arduino as platform, we had much fun putting these two devices together and let them talk to each other. This communication is used to keep the animation on both LCD displays in sync. There is a video below but it has a really bad quality. Focus your eyes on the LCD devices when watching it.

More information will follow in the next hours… ;)
